The symptoms of diesel bugs are easy to find. Important things to check over and look out for are: Blocked Filters; Fuel System Failure; Worn Fuel Injectors; Corroded Tanks; Engine Failure; Microbial contamination is significantly accelerated when higher biodiesel content occurs along with lower sulphur content.
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
The fuel injector is effectively a spray nozzle that performs the final stage in the delivery of fuel into the engine. The injector is located in the combustion chamber, inlet manifold or – less commonly – the throttle body. Fuel injectors which also control the metering are called injection valves, while injectors that perform all three ...
Some fuel injection computers interpret "pumping" the throttle to indicate a flooded engine, and alter the fuel-air mixture accordingly. In a carbureted engine equipped with an accelerator pump (which advances fuel flow to match air ingestion under rapid throttle acceleration), "pumping" the throttle will force excess fuel into the engine ...
British Airways Flight 38 crash-landed at London Heathrow in 2008 after its fuel lines became clogged with ice crystals.. In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading ...
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve, have mostly fallen out of favor to direct injection. However, certain ...
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine.
These valves are mounted on the outlet fittings of the fuel injection pump, one per cylinder injector. They are always mounted at the pump end of the pipes between the pump and injectors. The check valve aspect is a conical valve or 'mitre valve', [ i ] held against a matching conical seat by a spring.
